SF6 Gas Monitoring and Alarming Practices in Gas-Insulated Switchgear (GIS) Systems

The main reason for gas monitoring is to make sure there is enough SF6 gas to run the machinery. In most cases, this requires checking the gas density. However, there are caveats to measuring gas densities. One spot in the GIS system is often used to assess gas density, and that spot is the enclosure. (Figure 1).
